IP27 currently the only system that absolutely needs discontiguous
memory in order to work at all. A few other systems could make use of
discontiguous memory to reduce the waste of memory - the family of
Broadcom SB1 based systems comes to mind.

See IP27. IP27 has one added extra complexity, it's a NUMA system but
you can ignore that.
